Right to Buy fraud is becoming an increasingly big problem in London, new figures have revealed.
According to the London Boroughs' Fraud Investigators' Group, detected cases of Right to Buy fraud more than doubled to 300 during 2014-15.
This was worth £26 million during this period - which is 185 per cent higher than the figure recorded a year earlier.
As a result, the organisation believes at least three per cent of Right to Buy applications in the capital are dishonest.
The London Boroughs' Fraud Investigators' Group found that this is part of a much wider problem, with the value of fraud against councils in London overall rising by 46 per cent in 2014-15 to £75 million.
This is despite a ten per cent drop in the actual number of fraud cases being dealt with by local authorities in the area.
Kevin Campbell-Scott, chairman of the group and fraud manager at Southwark Council, said councils in London are currently "leading the way in the fight against public sector fraud".
However, he warned that new risks are constantly emerging. As a result, he believes local authorities must aim to "stay one step ahead of those who want to cheat the public purse.
Mr Campbell-Scott went on to praise fraud teams in the capital for their "sterling work", as they are taking "money and council houses back from fraudsters, so that they can benefit those in genuine need".
Some 1,618 properties in London were recovered from fraudsters during 2014-15. However, this was around half of the total recovered across the country as a whole.
The London Boroughs' Fraud Investigators' Group has therefore urged councils with low levels of detected fraud to think about whether they are focusing enough on this issue.
Indeed, it pointed out that those with the highest levels of non-benefit fraud prevention tend to have a "strong corporate commitment" to dealing with this problem in "proactive and innovative ways".
